When trying to use my discrete video card whole system freezes after couple of seconds and doesn't react on anything. I've tried to have a delayed killall -9 running in the background like "sleep 60 && killall -9 glmark2 &" but it seems to be never run or having no effect. Only hard reset helps.
Have Intel HD4000 + muxless Radeon 7730M

doesn't matter what to run, everything is going to die. kernel 4.3.3 + xorg 1.18.0, archlinux distribution, most recent at time of writing this post. Please let me know how to provide more data for you being able to debug this.
